I have a two-story redwood deck, which has lots of railing and, consequently, lots of little fence-like vertical posts that support the railing. A1 power-washed, sanded, re-stained and re-sealed everything except the little vertical posts for $5675, which was on par with what I was expecting to pay (other quotes I got 2-3 years ago were in the $5-6K range). Everything went smoothly, which I really appreciate - no missed appointments, no late arrivals, no last-minute rescheduling, no mistakes or oversights on the written estimate. I called in early March 2021 to schedule an estimate. Stuart, the owner, met with me in about a week and delivered a written estimate within a day. We scheduled the job to occur about six weeks later, and it went off exactly as I was told it would, thanks to Eliseo who actually did the work. I would highly recommend A1. They are skilled, reliable and fairly priced. I have worked with other businesses that don't have those qualities. It is such a relief to find a business like A1, and I would definitely recommend them.
